NOTES AND EXHIBITIONS. 



Jassid on Eragrostis sp. — Mr. Giffard exhibited specimens 

 of an undetermined Jassid collected on an Eragrostis near the 

 Halfway House, Kau, Hawaii, at 2500 feet elevation, on August 

 27, 1919. It is apparently the same species found by Mr. Gif- 

 fard on Eragrostis at Diamond Head, Oahu, several years ago. 

 Specimens have been sent to Professor Osborn for determina- 

 tion. Mr. Timberlake remarked that the flightless Jassid he 

 had taken on Haleakala, Maui, at 8000 feet elevation, shows 

 some points of resemblance to this species. Mr. Giffard spoke 

 further on the progress of Professor Osborn in his work on 

 Hawaiian Jassidae, and of Mr. Van Duzee in his work on the 

 Heteroptera. 



Coccus acutissimus Green. — Mr. Ehrhorn reported finding 

 this Coccid at Honolulu on litchi, and stated that it was a new 

 record for the islands, but that it had probably been here a 

 long time. It was recorded by Green on banana. 



Plutella on Lcpidium. — Mr. Bridwell spoke of finding a 

 Plutella on the native Lepidinm at Makapu Point. The cocoon 

 is similar to that of Plutella maculipennis and specimens when 

 reared may prove to be the same. 



Plagiihniysinc on Elacocarpus. — Air. Bridwell reported . a 

 plagithmysine larva which he had found in the dead bark of 

 Elacocarpus, well up in Makaha Valley, Waianae, Oahu. 



Brnchus limhatus. — ]\Ir. Bridwell recorded this Bruchid 

 breeding in the seeds of opiuma, and stated that he had found 

 it spread as far as Castner in the middle of the island, but not 

 yet on the far side of Oahu. 



Tephritis. — Mr. Bryan stated that he was working on this 

 genus and wished to examine more material. 



Trypoxylon sp. — ]\Ir. Williams reported that he had found 

 specimens of our small, unnamed immigrant Trypoxylon in the 

 Experiment Station collection, from Los Banos, Philippines 

 (Williams) and Hongkong, China (Terry), the species being 

 represented by one specimen from each locality.
